Abstract

To provide a button pressing aid attached to a jet spray can which helps elderly in using a spray, for solving problems for example, there are many types of sprays which are used by pressing by finger, a jet button, in household, for example, a cooking ignition spray used in a kitchen and a tree disinfection spray at a garden, however, due to aging, there are many cases in which, by nerve symptom, the hand of a user shakes and fingers are deviated from a button, and due to deterioration of muscles, one cannot strongly press the button.MEANS FOR SOLVING THE PROBLEM: To a spray can cylindrical container, a lower part of an acrylic board bent into a tunnel shape, is adhered, on an upper jet button facing position, a window which a forefinger can enter, is cut into a circular shape for opening. Therefore, the circular window on the acrylic board can hold the finger of a user pressing the jet button by its circumference for preventing the finger of the user from deviating from the jet button, in addition, an end (edge) of the circular window serves as a reaction resistance part for the finger pressing the button, thereby enhancing force of the finger pressing the jet button. In addition, by invention of many terms for example, pressing the jet button by the palm of the user by using a leverage rod instead of the forefinger and using the window colored by a fluorescent color for allowing a user to understand soon that there is the spray even in night. The invention can help elderly in using the jet sprays.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] This invention relates to a button pressing aid that can be attached to spray cans that are widely used in homes, such as emergency fire extinguishing sprays in the kitchen, tree disinfectant sprays in the garden, and toilet deodorizing sprays, which are sprayed by pressing the spray button with a finger. [Background technology]

[0002] There are two spray can methods for use at home. One is a lever handle type, which uses the entire palm of the hand to spray. The other is a finger press type, which uses the force of just the index finger to fire. The two types are sold almost equally on the shelves, but the finger press type is now becoming more popular due to its ease of storage and cost. This invention adds new technology to the finger press type. [Prior art documents]

[0003] The following prior art can be found in the field of solvent spraying from spray cans, but none of it is identical to the present invention. Jitsuzen Showa 51-023708 Finger lever type simple aerosol spraying device Patent Publication 2022-044077 Spray injection rod Summary of the Invention [Problem to be solved by the invention]

[0004] Spray cans are filled with various solvents tailored to the purpose, such as preparing for the initial extinguishing of a kitchen fire or disinfecting trees, along with liquefied petroleum gas (LPG) as a propellant. For this reason, the valve on the spray can is difficult to open and close, and the button needs to be pressed quite hard to spray. Meanwhile, a common symptom among the elderly is that "the hands shake and the fingers that press the button come off," or "the muscles have weakened and they are unable to press the button." This invention is an auxiliary device that can be attached to a spray can to help the elderly to spray. Means for solving the problem

[0005] In the invention of claim 1, the lower part of a tunnel-shaped acrylic plate is glued to the middle of the cylindrical spray can near the shoulder, and a circular window is cut out and opened at the top of the acrylic plate, facing the spray button, so that an index finger can enter and exit through it.

[0006] In the invention of claim 2, a lever bar that does not exceed the height of the spray can is temporarily attached to the cylinder of the spray can of claim 1, and anti-slip rubber is attached to both ends of this lever bar.

[0007] In the invention of claim 3, the circular opening of the index finger insertion window in the tunnel-shaped acrylic plate in the button pressing aid of claims 1 and 2 is left connected to the acrylic plate by simply making a cut in the lower half of the circumference, and this is bent toward the injection button to form a canopy for the window opening in the acrylic plate.

[0008] In the invention of claim 4, a fluorescent or vividly colored edging sponge is attached to the cut surface of the window to be made in the acrylic plate of claims 1 to 3.

[0009] In the invention of claim 5, a hole is drilled along the shoulder line of the spray can in the tunnel-shaped acrylic plate of the spray can of claims 1 to 4.

[0010] The present invention has the following excellent effects: (1) The edge of the circular opening supports the finger that is pointing at the spray button, preventing people with trembling fingers from accidentally removing the button. (Claim 1) (2) People who cannot use their fingers at all can press the button by using a lever that is temporarily attached to the spray can cylinder instead of their index finger. (Claim 2) (3) The visor that is bent from the semicircular window toward the injection button acts as a repulsive force against the finger pressing the button, making the force of the finger pressing the button stronger. (Claim 3) (4) The fluorescent sponge edging attached to the cross section of the acrylic plate opening clearly indicates the location of the window where the fingers are inserted, even at night, and the soft sponge prevents scratches on the fingers. (Claim 4) (5) If you have no problem with finger strength, you can cut off the unnecessary upper part of the acrylic sheet using a drilled hole along the shoulder line of the tunnel-shaped acrylic sheet spray can and discard it. (Claim 5) [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The embodiment of each claim will be explained with reference to the drawings. The embodiment of the invention of claim 1 will be explained with reference to FIG. 1. First, the platform of this invention will be explained. The platform is made of plastics such as acrylic and polycarbonate (hereafter, acrylic will be used uniformly). Acrylic has a high degree of transparency, so the user can see the index finger 7, the finger push button 3, the nozzle 8, and the spray 9. A small piece is cut out from the acrylic material to create a flat plate of the size of this invention. Since a household spray can 1 is intended to be held in the hand, spray containers are often made into a cylindrical shape with a diameter of about 6.5 cm and a height of about 20 to 25 cm. Therefore, the size of the acrylic flat plate attached to a part of the side of the spray can 1 of this invention (about a quarter) is preferably a rectangular size with a horizontal dimension of a quarter of the cylindrical circumference, i.e., about 5 cm, and a height dimension of about 10 cm.

[0013] The acrylic plate is processed. First, heat is applied to the acrylic plate so that it adheres perfectly to the cylinder, and it is bent into a round shape like a tunnel. This creates a tunnel-shaped acrylic plate 5 that fits tightly around the spray can 1. Next, holes are drilled into this tunnel-shaped acrylic plate 5. As a preliminary step, the opening position is marked out. To do this, while holding the tunnel-shaped acrylic plate 5 against the spray can 1, a circular window 6 is marked out opposite the finger press button 3, so that the index finger 7 can easily enter and exit. Once this point is opened, the processing is complete.

[0014] Attach the tunnel-shaped acrylic plate 5 to the spray can 1. Strong industrial double-sided tape is attached to the back side of the tunnel-shaped acrylic plate 5 that comes into contact with the spray can 1, so peel off the release liner from the tape and firmly attach the bottom of the tunnel-shaped acrylic plate 5 to the part below the spray can shoulder 2. This completes the button pressing aid that can be attached to the spray can 1.

[0015] How to use it is explained with reference to Figure 2. It is very simple to use; just insert your index finger 7 into the circular window 6 and use your fingertip to press the finger push button 3. The edge of the circular window 6 tightly encases your index finger 7, so that your index finger 7 will not come off the finger push button 3.

[0016] The implementation of claim 2 is explained with reference to Fig. 3. This invention is aimed at people who do not have enough finger strength, and therefore implements the following two measures. The first is to prepare a lever 11 that is within the height of the spray can 1 on the side of the spray can 1 of claim 1 and temporarily attach this to the cylinder of the spray can 1 with tape or the like. The second is to attach non-slip rubber 15 to both ends of the lever 11.

[0017] How to use it is explained with reference to Figure 4. When using spray can 1, a person lacking finger strength removes lever 11, which is temporarily attached to spray can 1, from tunnel-shaped acrylic plate 5, and inserts one end of lever 11 into circular window 6, with the tip of lever 11 gripping finger push button 3. Next, place the other end of lever 11 on palm 16 and lift in the direction of arrow 17. The edge of circular window 16 now becomes the fulcrum of the lever, and both tips of lever 11 become the force points of the lever, and the leverage of these three points allows finger push button 3 to be pressed hard. For this reason, anti-slip rubber 15 is attached to both ends of lever 11, where force is applied, to prevent slipping.

[0018] The implementation of claim 3 will be explained with reference to Figs. 5 and 6. Fig. 5 shows spray can 1 from the front, and Fig. 6 shows spray can 1 from the side. Claim 3 is an invention in which index finger 7 itself is used as lever 11 to push finger button 3 a little harder. For this reason, the circular opening of the index finger insertion window of the tunnel-shaped acrylic plate as in claims 1 and 2 is limited to simply cutting a cut in the lower half of the circumference of the circle, so that the opened window also becomes a semicircular window 13. The cut lower half acrylic is connected to tunnel-shaped acrylic plate 5, and is bent toward the spray button to form eaves 14 for semicircular window 13 opened in tunnel-shaped acrylic plate 5.

[0019] When using the spray can 1 of the present invention, the joint area of ​​the index finger 7 inserted through the semicircular window 13, where the most force is applied, hits the wide repulsive resistance area created by the visor 14 of the semicircular window 13, making the force with which the button is pressed stronger.

[0020] The embodiment of claim 4 will be explained with reference to Fig. 7. In the embodiment of this invention, the cut surfaces of the acrylic plate of the circular window 6 and the semicircular window 13 to be made in the tunnel-shaped acrylic plate 5 are edged with fluorescent colored edging sponge 10 instead of rubber.

[0021] This is extremely useful in the event of a kitchen fire at night, etc. The index finger 7 insertion window is made visible to alert anyone who is in a hurry, and the sponge effect prevents scratches on the finger even if the index finger 7 is inserted and removed in a hurry.

[0022] The implementation of claim 5 will be explained with reference to Fig. 8. Claim 5 is an invention proposed to spray can manufacturers. The inventions of claims 1 to 4 described so far are inventions that ask people with poor finger condition to also purchase a separately sold finger pressing aid when purchasing spray can 1. However, considering the coming aging society, this invention proposes to manufacturers that spray can 1 be manufactured with an aid attached from the manufacturing stage.

[0023] For this purpose, the tunnel-shaped acrylic plate 5 has a drilled hole 12 drilled along the ridge of the spray shoulder 2. Most people who have no problems with their fingers and do not need any assistive devices can use the tunnel-shaped acrylic plate 5 by cutting off the upper part at the drilled hole 12. [Industrial Applicability]

[0024] As our lives become more diverse, sprays will be used not only for early firefighting and tree disinfection, but also for sports, leisure, medical, clothing, industrial, and other aspects of daily life. More importantly, the number of elderly people will peak at 38 million in 20 years, and the need for this invention's auxiliary device will increase even more. [Explanation of symbols]
